fix: avoid ERR_TLS_CERT_ALTNAME_INVALID when redirected url

[azu]

Always set valid HOST for fetch's url.

Error on following case:

1. https://example.com
2. Redirect => https://new.example.com/

First fetch's Host is example.com, but Second fetch's Host should be new.example.com.

Current use same Host for new.example.com. It is invalid host name.

Invalid Host make following Error

13:124 error https://www.consul.io/intro/getting-started/kv.html is dead. (request to https://learn.hashicorp.com/consul/getting-started/kv.html failed, reason: Hostname/IP does not match certificate's altnames: Host: www.consul.io. is not in the cert's altnames: DNS:*.netlify.com, DNS:netlify.com) no-dead-link
